Apollo Test
Creating Infra
To create an infra first modify the terraform.tfvars file. Insert the appropriate values for the keys.
Run ./apollo-test.sh create-infra
This will create the VM, VPC, subnet, firewall, and a GKE cluster.
Deploying ansible
This script uses terraform ansible provider.
Please download and setup the plugins in your ~/.terraform.d/plugins/ folder.
After that run ./apollo-test.sh deploy-nginx
This will deploy a nginx in the VM created in the previous step. Deploy a hello-world application.
Clone the hello-world repo.
Dockerfile is present inside that repo itself. The docker image has been built and put in the docker hub repository.
If you still want to build your docker image, go inside helloworld folder and run docker build -t <whatever-tag> . and push the docker image to a public repo with command docker push <whatever-tag>.
Now update the docker-image name in terraform.tfvars and run terraform apply before deploying the nginx using ./apollo-test.sh deploy-nginx
Deploying into K8s
Clone the hello-world repo as mentioned above.
Now the gke is create when we ran ./apollo-test.sh create-infra. So, we just need the kube config file.
To do that install gcloud.
Run gcloud init. This will ask you to login into your google account and set your default project.
Now set the kube config by running gcloud container clusters get-credentials <cluster-name> --region <cluster-region> --project <gcp-project>.
Now once the kubeconfig is initialized. Just go inside the hello-world folder and run helm upgrade --install helloworld ./helloworld.
You can install helm using this doc.
